Despite the wide variety of agendas used in legislative settings, the literature on sophisticated voting has focused on two formats, the so-called Euro-Latin and Anglo-American agendas. In the current paper, I introduce a broad class of agendas whose defining structural features,...

We study the possibilities for agenda manipulation under strategic voting for two prominent sequential voting procedures: the amendment procedure and the suc- cessive procedure. We show that a well known result for tournaments, namely that the successive procedure is (weakly) more manipulable...

The paper considers a voting model where each voter's type is her preference. The type graph for a voter is a graph whose vertices are the possible types of the voter. Two vertices are connected by an edge in the graph if the associated types are "neighbors." A social choice function is locally...

The main purpose of the present paper is to disentangle the mix-up of the notions of success and satisfaction which is prevailing in the voting power literature. We demonstrate that both notions are conceptually distinct, and discuss their relationship and measurement. We show that satisfaction...

Power is a core concept in the analysis and design of organizations. One of the problems with the extant literature on positional power in hierarchies is that it is mainly restricted to the analysis of power in terms of the bare positions of the actors. While such an analysis informs us about...

Collective-choice rules aggregate individual choices into a group choice. This study addresses the role of collective-choice rules in a social dilemma situation in which group members can repeatedly choose a combination of institutions to achieve self-governance. Specifically, we investigate...

We examine the consequences of vote transparency in committees whose members fear being blamed by partisan observers for casting an unfavorable vote. We show that such social pressure, like optimal taxation, can improve the collective decision by mitigating a voting externality. Hence,...

Under the plurality voting rule we often see that a party forms the government by winning majority of the seats, without winning majority of the votes. In some situations a smaller party with lower vote share may win more seats than a party with larger vote share. A more problematic case is when...

We develop an analysis of voting rules that is robust in the sense that we do not make any assumption regarding voters' knowledge about each other. In dominant strategy voting rules, voters' behavior can be predicted uniquely without making any such assumption. However, on full domains, the only...
